Column Width in Matrix Resizes Even When Auto Size turned OFF

I have experience this same issue with the total column in a matrix.  All other columns seem to remain fixed as intended; however, when a new slicer value is selected and the dependent matrix refreshes the grand total column on the matrix usually gets crunched down so that the height of the entire matrix exceeds the alotted space (since row heights get doubled).  It's quite annoying because you have manually adjust the total column each time you want to look at new data.
